Types

type Distributor 

type Distributor struct {
	// contains filtered or unexported fields
}

Distributor distributes notifications to a list of subscribers (event consumers).

It allows thread-safe subscription of multiple consumers to events.

type QCCreatedDistributor added in v0.23.9 

type QCCreatedDistributor struct {
	// contains filtered or unexported fields
}

QCCreatedDistributor ingests events about QC creation from hotstuff and distributes them to subscribers. Objects are concurrency safe. NOTE: it can be refactored to work without lock since usually we never subscribe after startup. Mostly list of observers is static.

func NewQCCreatedDistributor added in v0.23.9 

func NewQCCreatedDistributor() *QCCreatedDistributor

func (*QCCreatedDistributor) AddConsumer added in v0.23.9 

func (d *QCCreatedDistributor) AddConsumer(consumer hotstuff.QCCreatedConsumer)

func (d *QCCreatedDistributor) OnQcConstructedFromVotes(qc *flow.QuorumCertificate)

type TimeoutCollectorDistributor added in v0.29.0 

type TimeoutCollectorDistributor struct {
	// contains filtered or unexported fields
}

TimeoutCollectorDistributor ingests events from hotstuff and distributes them to subscribers. Concurrently safe TODO: investigate if this can be updated using atomics to prevent locking on mutex since we always add all consumers before delivering events.

func NewTimeoutCollectorDistributor added in v0.29.0 

func NewTimeoutCollectorDistributor() *TimeoutCollectorDistributor

func (*TimeoutCollectorDistributor) AddConsumer added in v0.29.0 

func (d *TimeoutCollectorDistributor) AddConsumer(consumer hotstuff.TimeoutCollectorConsumer)
